Cytokine and chemokine production by B henselae–infected DCs. Immature DCs untreated (iDCs), infected with B henselae (B. henselae–DCs), or treated with 100 ng/mL LPS (LPS-DCs), were cultured for 24 hours. Supernatants were collected and tested for indicated cytokine and chemokine production by specific ELISA. Data are the average determination ± SD of 4 independent experiments. *Statistical difference as assessed by statistical analysis (P < .05).
